1. Decrypt these messages that were encrypted using the Caesar cipher. a) EOXH MHDQV b) WHVW WRGDB c) HDW GLP VXP 2. Suppose that the ciphertext DVE CFMV KF NFEUVI, REU KYRK ZJ KYV JVVU FW JTZVETV was produced by encrypting a plaintext message using a shift cipher. What is the original plaintext? 3. Encrypt the message GRIZZLY BEARS using blocks of five letters and the transposition cipher based on the permutation of (1, 2, 3, 4, 5) with o(1) = 3, 0(2) = 5, o(3) = 1, 0(4)=2, and a(5) = 4. For this exercise, use the letter X as many times as necessary to fill out the final block of fewer than five letters. 4. Decrypt the message EABW EFRO ATMR ASIN which
